| Abstract: | By use of the ultrasonic pulse echo overlap technique, the elastic moduli of isotropic polycrystalline AI.Cu and Ta.and their pressure derivatives have been determined. The isotherms for these three metals, calculated from Birch-Murnaghan e-quation of state are also compared with the shock wave isotherms. |

| Keywords: | elastic modulus equation of state isotherm |
